Erlang Language Module for BBEdit v1.4, (2018/01/14)

The Erlang Language Module introduces syntax colorization, auto-completion, function navigation and code folding for the Erlang programming language to BBEdit 11 and higher.

It recognizes the following Erlang files:

  • erlang source code (.erl)
  • erlang include files (.hrl)
  • escript scripts (.escript)
  • application files (.app)
  • application upgrade files (.appup).

Please use Erlang Language Module v1.2 for BBEdit 9 and BBEdit 10.

Inline help through auto-completion

Erlang Language Module main feature consists in providing inline help through BBEdit completion feature. When typing calls to functions in OTP modules, Erlang Language Module displays the actual argument order with the names of the arguments as well as the return values as described in the documentation.

Download

The binary can be downloaded from GitHub: https://github.com/pguyot/erlang-bblm/releases/tag/v1.4

Installation

To install the plug-in, simply double-click it or drop it on BBEdit. This will launch BBEdit (or bring it to the front) which will then ask if you want to install the plug-in and relaunch BBEdit.

Alternatively, you can put it manually into "~/Library/Application Support/BBEdit/Language Modules/".

Source code and compilation

The plug-in can be compiled with XCode and BBEdit SDK.

Source code is available on GitHub: http://github.com/pguyot/erlang-bblm

The plug-in was compiled with the preview version of the SDK. You can obtain it by e-mailing support@barebones.com until it is released.

Build Status

(Build fails as the plug-in is incompatible with the current SDK release)

Current limitations

  • The module does not detect Erlang content. This would be nice to automatically detect Erlang term files such as rebar configuration files.

  • The module parses functions and attributes properly as long as the code follows standard Erlang practice of declaring functions and attributes immediately after a new line, and having the rest of the code somewhat indented. In other words, the parser is just a quick and dirty implementation that should usually work as expected. As you might expect, the language module is not robust to interesting uses of parse_transform/2.

  • The module simply ignores pre-processor directives. This means it can be confused by pre-processor magic. Macro invocations are colorized, even if they are not properly defined.

  • edoc tags are detected and colored, but not their arguments. Actually, anything starting with @ in a %% comment is colored (triple % works, too). Maybe at some point, the module will only color valid @ tags.

  • There is no completion with parameters of functions in the current module, especially those with specifications.

  • I didn't exploit the folding types yet. Plus folding always happen for the whole function, not for individual clauses.
